The addition of Re to Pt/ZrO2 improved the catalyst stability and product selectivity. Reaction temperature greatly affected not only reaction efficiency but also product distribution. n-Propylbenzene was obtained in up to 73% yield with ca. 80% selectivity. After the reaction, the catalyst was deactivated possibly due to water-induced wrapping of Pt nanoparticles in ZrO2. The reaction may involve the hydrogenation of 4-propylphenol to 4-propylcyclohexanol, followed by the dehydration to give 4-propylcyclohexene and the subsequent dehydrogenation to n-propylbenzene.ElsevierJournal Articleapplication/pdfhttp://hdl.handle.net/2115/56868https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/56868/1/CatalToday_234_139.pdf0920-5861AA10677070Catalysis Today2341391442014-10-01enginfo:doi/10.1016/j.cattod.2014.01.022author
